Direct and indirect arsenic release from soaps by unhygienic use in tubewells

Microorganisms have been implicated in the release of arsenic into drinking water involving bio-electrochemical reactions. Iron reducer has been shown to release captive arsenic from insoluble ferric oxyhydroxide–arsenic oxide adduct. Sulphate reducing bacteria (SRB) and Enterobacteriaceae may play a similar role by releasing hydrogen sulphide. The case of arsenic mobilization in water may be complex and varied. Arsenic contamination in Kanpur, northern India, 1000 […]
